I don't know where you take your informations, jake austin, but no ABS, automatic gearbox, traction control or other airbags in today's traditional mogs (4/4, +4, tourer and V6 roadster)
(the story is different for the more modern "aero line", obviously)
Regarding the engines and their evolution I remind you that MMC never built any engine in all its history. They bought what they thought to be the best for their car from external manufacturers: peugeot, ford, fiat, etc etc etc...
It's logical that they stuck to an existing offer for their choices of engine.
The buick/rover V8 was a real modern aluminium engine in its time.
Change the engine when it's necessary and keep the traditional shape and architecture of the car could maybe be seen as the identity of Morgan.
Furthermore, modern engines with injection and catalythic exhaust in traditional mog is the key of their compliance with the contemporary rules about air pollution, and the reason we can always buy and drive them in our modern world.
As a conclusion I would say that a 1938 4 wheels morgan is too modern for a 3 wheeler fan, and a 1960 4/4 is maybe a "caricatures of the originals" for a flat rad lover...
